Nice explanation on the poem :)
Also interesting discussion on the topic whether Viaan is in love or he is just getting open to love or at what point is he in realisation that he is in love with Katha... Sequence of poetry which I must say is very rare for any indian show to express falling in love that too for a male lead was to me actually his realization that yes he is in love.. after so many episodes of showing the steps that his mumma told him about love and deciphering his feelings yet for this woman he finally reached a conclusion through this poetry scene.
Now at what point is he in love.. hehe love is a journey.. the way he describes that he feels alive thinking that Katha has now started talking to him.. shows that gullible side of love.. fresh feeling of love.. innocent love.. very start of it.. You feel special because the person you love acknowledges you and shares her feelings with you.. in that scene he begins with their dark night argument flashback.. his expression showed how disgusted he feels about that start of their equation.. He was filled with darkness at that time and how a little hope came in his life when things started changing between them... step by step.. he acknowledges that she brings hope in his life.. hope that trusts are not always broken.. hope that there is love in this world.. and he has started to feel for her.. to me this is just start of his journey.. his opening up to idea of love for Katha.
